Panasonic Lumix DMC-GX8
The Panasonic Lumix DMC-GX8 is a digital rangefinder-styled mirrorless interchangeable-lens camera announced by Panasonic on July 16, 2015. The camera features a newly developed 20 megapixel sensor - previously the highest resolution in Micro Four Thirds cameras was 16 megapixels. The camera's ISO range touches 25600 and it can capture continuous frames at up to 8 frames per second. One major new feature introduced in the camera is "Dual IS", the camera 5 axis image stabilisation gets synchronised, when available, with lens based image stabilisation. The camera also records 4K video, but with addition crop around 1.6x. The manufacturer has indicated the time to acquire auto focus as 0.07 seconds. The electronic OLED viewfinder has a resolution of 2.36 million dots and, as in the predecessor, is tiltable. The OLED touchscreen rear display is fully articulated and can display 1.04 million dots. The camera is splash proof. A smaller version of the GX8, the Panasonic GX80 (retaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panasonic Lumix DMC-GX7
The Panasonic Lumix DMC-GX7 announced in August 2013, is a Micro Four Thirds compact mirrorless interchangeable lens camera. It was Panasonic's first Micro Four Thirds camera with a built-in in-body stabilization system (IBIS) and has a built-in EVF (add-on EVFs are no-longer supported). Panasonic uses 2-axis in-body stabilization allowing the use of shutter speeds 1 to 2 stops slower than without stabilization, compared to the 4 to 5 stops of improvement offered by Olympus' 5-axis stabilization. Features include: * Magnesium alloy body * New 16 MP Live MOS, Four Thirds sensor (25% better Signal to Noise performance, 10% better sensitivity, 10% better saturation level ) * Venus Engine * ISO 200 - 25,600 (ISO 125 in extended mode, max. 3,200 in movie mode) * Maximum shutter speed 1/8000 sec. * AF detective range: -4 EV to 18 EV Lumix GX7 Review Part 2 – Sensor, Shutter and In Body Stabilizatio"Lumix GX7 Review Part 2 – Sensor, Shutter and In Body Stabilization" * Micro Four T ...

Mirrorless Interchangeable-lens Camera
A mirrorless camera is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera, but may have an electronic viewfinder. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount. Terminology Mirrorless cameras are sometimes referred to as mirrorless interchangeable-lens cameras (MILC), or digital single-lens mirrorless (DSLM) cameras. This latter name highlights their connection to DSLRs. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs). Overview Mirrorless cameras are mechanically simpler than DSLR cameras, and are smaller, lighter, and quieter due to the elimination of the moving mirror. While nearly all mirrorless cameras have a mechanical shutter, many also have an electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panasonic
formerly between 1935 and 2008 and the first incarnation of between 2008 and 2022, is a major Japanese multinational corporation, multinational Conglomerate (company), conglomerate corporation, headquartered in Kadoma, Osaka, Kadoma, Osaka Prefecture, Osaka. It was founded by Kōnosuke Matsushita in 1918 as a lightbulb socket manufacturer. In addition to consumer electronics, of which it was the world's largest maker in the late 20th century, Panasonic offers a wide range of products and services, including Rechargeable battery, rechargeable batteries, automotive and avionic systems, industrial systems, as well as home renovation and construction. Panasonic has a primary listing on the Tokyo Stock Exchange and is a constituent of the Nikkei 225 and TOPIX, TOPIX 100 indices. It has a secondary listing on the Nagoya Stock Exchange.

OLED
An organic light-emitting diode (OLED or organic LED), also known as organic electroluminescent (organic EL) diode, is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as smartphones and handheld game consoles. A major area of research is the development of white OLED devices for use in solid-state lighting applications. There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix (AMOLED) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Low-pass Filter
A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. A low-pass filter is the complement of a high-pass filter. In optics, high-pass and low-pass may have different meanings, depending on whether referring to frequency or wavelength of light, since these variables are inversely related. High-pass frequency filters would act as low-pass wavelength filters, and vice versa. For this reason it is a good practice to refer to wavelength filters as ''short-pass'' and ''long-pass'' to avoid confusion, which would correspond to ''high-pass'' and ''low-pass'' frequencies. Low-pass filters exist in many different forms, including electronic circuits such as a hiss filter used in audio, anti-aliasing fil ...
